Synthesis of Mesoporous Calcium Silicate by Template Method and Its Adsorption Characteristic for Pb2+

Abstract

Abstract. Mesoporous calcium silicate (MCS) was synthesized by template method using calcium nitrate tetrahydrate and sodium metasilicate nonahydrate as raw materials, cetyl trimethyl ammonium bromide-tetramethyl ammonium hydroxide as template. Its structure was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Brunuaer-Emmett-Teller (BET) surface analysis, and scanning electron microscopy (SEM
